MICHAEL ILITZ. OF MANILA, PHILIPPINE ISLANDS. h

FIELD-RANGE.

Application led December 26, 1913.

To all whom t may concern.'

Be it known that I, 'MICHAEL ILrrz, a citizen of the United States, residing at Manila, island of Luzon, Philippine Islands, have invented certain new anduseful Improvements in Field-Ranges, of which the following is a specification.

This invention relates to stoves and particularly to a knock-down or separable field range which may be readily moved from place to place in the 1form of a balanced pack for mule or like transportation and quickly assembled and disassembled.

My present invention is especially adapted for army use, although I do not, of course, limit it to such use but only mention it by way of reference here at the outset as illustrative of imposed conditions which my improved range is peculiarly adapted to meet. Owing to the difficult nature of the conditions and problems presented in the service, considerable difficulty has been experienced in devising a field range which will satisfactorily meet official requirements and test conditions. Before entering into -a more particular discussion of my invention, however, and in order that its advantages and features of merit may be more readily appreciated, it will perhaps be well to rst briefly enumerate the principal conditions and requirements to which a field range is actually subjected in field service.

These requirements are, briefly, facility of transportation, quickness and ease of assemblage and disassemblage, economy of fuel, lightness and compactness of parts combined with unusual durability and strength, complete sanitation and ample cooking capacity for satisfactorily preparing large quantities of different food articles simultaneously, as well as afterward quickly and completely incinerating the camp refuse.

To the end, therefore, of providing a field range which will satisfactorily and completely meet these vunusual conditions of use, I have devised my present invention.

The construction and principle of my invention will be more'fullydisclosed in the specification which follows. In the drawings which form a part of that specification I have shown as an illustrative embodiment a construction which not only clearly illustrates my invention but is, in itself a form proven to be of the greatest utility under practical test.

Fig. 14 is a detail view showing the manner of nesting the joints of the stove pipe when ready for transportation.

The field range made in accordance with my present invention comprises essentially two spaced sections indicated in the drawings by reference numerals l and 2 respectively, the section l `providing thel ovenI proper in which the grate, fire plate, bake pans, and sections of' the smoke stack are stored for transportation and the section 2 the reservoir in which the nested'boilers and kitchen utensils are stored. For convenience of description hereinafter Vwhen reference to the oven section is made it will be understood that the section 1 is meant and similarly with the reservoir section 2.

The two sections being spaced define a re box 2 and are joined together by a collapsible [ire plate 3 which bridges the lire space and connects with the sectional smoke flue 4.

I shall first describe the oven section 1.

This section is in the form of a hollow container and is made of some sheet material, preferably Russian iron. In practice it has been found desirable to cover the oppositely disposed inner walls of the oven and reservoir sections which face the lire box and the flue chamber of the fire plate with some fire resisting material, as asbestos. This covering I have indicated at 5.

The outer wall of the oven section is reinforced along its bottom and front faces by angle strips 6 which define at the front a door opening covered by a hinged door 7 A having a handle bail 8 and a suitably guided sliding latch member 9 slotted at its upper end to engage over a cooperating keeper 10 on the top facing strip.

Supported within the container by the spacing studs 11 is an internal lining 12 defining with the outer walls of the container a heat circulating passage 13 which is divided at a desired point by longitudinal partitions 14. To the inside face of the lining angle strips 15 are fastened and provide bearings for a grid-like supporting member 1G upon which rests one of two bake pans 17. The lining at its rear is flanged and to these flanges and to the top, bottom and side walls of the container is secured an end closure 18 having a handle bail 19 (see Fig. 13).

From this it will be seen that a heat circulating passage around the bake pans is provided. This passage at the top of the container connects with the atmosphere by two or more openings 20 cut therethrough and controlled by suitable slides 21 sliding in suitable guide-ways 21 secured to the under face of the top wall of the container. These holes may provide either additional cooking space or may be used to regulate the circulation of heat.

The heat circulating passage is connected at its top with the fire place by a plurality of heat admission openings 22 cut out of the side wall of the container and by a larger opening 23 below said series of openings. Along the top edge of the metal thus left by thc openings 22 I secure an angle strip 24 the horizontal portion of which has a plurality of alined relatively short slots 25 which receive depending guide flanges 26 formed along the top wall 27 of the collapsible fire plate 3 connecting the sections 1 and 2. At the rear end of this angle strip a second guide strip 28 is vertically arranged which strip is channeled as at 29 to receive the edges of the rear wall or section 30 of the fire plate.

This fire plate comprises three sections or walls7 a top wall 27, a rear wall 30 and a front wall 31,` the walls 30 and 31 being hinged to the top wall 2T.

The top wall 27 has two or more openings 32 covered by suitable slides 33 guided in ways 84 fastened to the under face of the wall and limited in their movement by stop flanges 35 disposed transversely of the wall and intermediate of the ways 34. These holes provide additional cooking space and ipay act as draft openings in 'starting the re. y

The front wall 31 carries a sliding damper 3G which slides in the lateral guides 37 formed by turning in the metal of the wall on two edges. This door has a pivoted latch and handle member 38 perforated at 39 for locking engagement with a pin 40 on the wall 31.

The rear wall 30 guides in the channel 29 of the guide strip 28 and has an anglcshaped piece 41 secured thereto and dening with said wall a chimney flue 41 (see Fig. 7). This flue on one face is covered with asbestos. Thatpart of the wall 30 adjacent the flue is cut out to provide a chimney vent. Fastened to the wall 30 on three sides of this vent are guide strips 42 in which is guided the base of an elbow joint 43 which forms the first section of the sectional smoke stack 4. The remaining sections 44 are of gradually decreasing diameter crimped at one end 45 for engagement with the unformed end of the contiguous section next above and terminating at the top in a second elbow 46. This construction provides for nesting the sections for transportation (see Fig. 14) which sections together with the elbows may be conveniently placed in onel of the bake pans as shown in Fig. 18.

The reservoir section 2 of my range7 unlike the other section has no heat circulating passage. Instead it is formed without a bottom and a portion of the inner side wall (which wall is covered with asbestos) is cuty away as indicated at 47, to admit heat from the fire place 2. A second heat admission opening 48 is formed in this side wall and corresponds to the similar opening 23 in the section 1. The metal of the side wall adjacent the cut-out portion 47 is turned to provide a longitudinally extending bearing flange 49 for a plurality of cross bars 50 to which are fastened suitably shaped supporting feet 51 (see Figs. 11 and 12.) The cross bars support boilers 52. These boilers are provided in a set Vof graduated capacity and made to t one within another so that they may nest for transportation purposes (see Fig. 12). The walls of the container are reinforced internally by angle strips 53. Like the section 1 the edges of the container are reinforced by suitable angle strips and a laterally swinging cover 54 is hinged to the top edge of one of these strips.

This section is connected with the section l by the fire plate 3 which engages in guides 2l and 28 similar' to theV guides 24: and 28 respectively of the section l.

In assembling my range, the sections l and 2 are first placed on the ground at a slight distance apart. The fire plate 3 is then removed from its storage place in one of the bake pans and is engaged in the guides 2 and 2S and 24 and 2S of the respective sections. The smoke stack is now removed and set up. The'range is now ready. This operation has taken about two minutes.

From the foregoing description taken in connection with the accompanying drawings it will be seen that my sanitary held range is composed essentially of two sections, an oven proper and a tank section and that these sections are joined together by a collapsible tire plate provided with a door in the front and a chimney in the rear; that the reservoir section is so constructed that a number of boilers can be nested therein, into the last boiler all of the kitchen utensils can be stored; that the oven proper provides for the storage of one grate and two bake pans, in one of which bake pans the collapsible fire plate can be stored and in the other` of which pans the nested elbow joints and pipe lengths of the stove pipe can be stored; and that when completely packed and ready for transportation the range consists of but two bundles which are preferably wrapped in canvas and strapped to the aparejo of a pack animal, thus equally distributing the weight of the range.'

It is of course possible to vary somewhat the structural details and relative arrangement of parts but successful practice has proven that best results are had with a range constructed and arranged as shown. I do not however, limit myself to the precise arrangement shown but regard as within my invention all modifications and amplifi cations within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

l. A collapsible stove comprising spaced Copies of this patent may be obtained for ve cents each, by addressing the Commissioner cooking units having vertically disposed channels on their opposed walls and having longitudinally extending slotted members along the upper edges lof said walls, and a sectional fire-box member having the opposite edges of a section thereof disposed for engagement in said channels and having depending flanges on the opposite edges of another section thereof disposed for interlocking engagement in the slots of said slotted members whereby to detachably connect said units.

2. A collapsible stove, comprising a pair of spaced cooking units, a collapsible fireboX section connecting said units, andan angle member deining with adjacent portions of said section a stack iue adapted to receive a portion of a smoke stack.

3. In a collapsible stove, a pair of spaced cooking units having outlet openings in their opposed walls, an intermediate collapsible structure detachably connecting said units and forming with said opposed walls an inclosed fire chamber, andV a member dening with said collapsible structure a flue common to the outlet openings of both units.

4. A collapsible stove comprising a pair of cooking units having substantially oppositely disposed outlet openings near the upper rear portions of their opposed walls, a sectional structure detachably connecting said units and forming with said opposed walls an inclosed lire-chamber, and a partition forming with the rear and top sections of said sectional structure a stack flue disposed between the outlets of said units and in communicating relation therewith.

5. A fire-box element consisting of a top section and front and rear sections movably connected with the top section, and a member secured to said rear section and contacting with said top section and defining therewith a stack flue. p

In testimony whereof I aliix my signature in presence of two witnesses.
